LT6654BIS6-3.3#TRPBF

Voltage Reference Overview

The LT6654BIS6-3.3#TRPBF is a precision series voltage reference from Analog Devices, offering a fixed 3.3V output with ±0.1% initial accuracy and a maximum temperature coefficient of 20ppm/°C. It operates within an extended industrial temperature range of –40°C to 85°C and supports input voltages up to 36V. The device features low dropout characteristics, low noise performance, and a buffered output capable of sourcing and sinking ±10mA. Packaged in a compact 6-lead TSOT-23 format, it is designed for high-accuracy applications requiring stable voltage regulation.

Voltage Reference Feature Summary

• Provides high-precision voltage regulation with curvature compensation technology
• Features a buffered output stage for robust load driving capabilities
• Operates efficiently with minimal voltage drop across the input-output terminals
• Delivers low-noise performance to minimize measurement uncertainty

Voltage Reference Applications

• Automotive control and monitoring systems
• High-temperature industrial sensing and process control
• High-resolution data acquisition systems
• Precision regulators and instrumentation equipment

Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm that the 'I' grade designation corresponds to the required –40°C to 85°C operating temperature range for your application environment. Ensure compatibility with the 6-lead TSOT-23 footprint during PCB layout. Check for any automotive-specific variants if AEC-Q100 qualification is mandatory for your project.

Voltage Reference Selection Notes

Select this component when a fixed 3.3V reference with ±0.1% accuracy is sufficient. Choose the 'I' grade variant specifically for industrial environments limited to 85°C maximum junction temperature. Consider the 'H' or 'MP' grades if operation beyond 85°C is required. Evaluate the low dropout voltage against your minimum supply headroom requirements.

Voltage Reference Part Context

This part belongs to the LT6654 family of wide supply, high output drive references. The family includes various accuracy grades (A, B) and temperature ranges (I, H, MP). The LS8 package option offers hermetic stability, while the S6 package provides a low-profile surface mount solution. All variants share core architectural features including low thermal hysteresis and long-term drift specifications.
